HANDLE-BAR FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 566,581, dated August 25, 1896.

Application filed November 5, 1895. Serial No. 568,070. (No model.)

To afl/ 107mm, it 72mg/ concer/v,.-

Be Ait known that I, DAVID S. HITCHCOCK, oi3 Cleveland, in the county of Oujf'ahega and State of Ohio, have invented certain new and useful Improvements in Handle-Bars for Bicycles, Ecc. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to malte and use the same.

My invention relates to bicycle-handles,

which are used to direct or steer bicycles, and

it consists in the peculiar construction of the socket of the handle-bar in connection with the upper end of the stein or steering-post, whereby the handle may be adjusted to difterent desired positions up or down.

In the drawings, Figure 'l is a view in side elevation ofV a steering-post of a bicycle with handle attached, showing in section a portion of the socket of the handle-bar. This view also shows the handle-bar raised to its highest position. Fig. 2 is a view illustrating the handle-bar in connection With the steeringpost, showing the handle-bar in its second elevated position. Fig. 3 is a View showing the handle-bar in its rst dropped position, and Fig. ai is view showing the handle-bar in its lowest position. Fig. 5 illustrates the socket of the handle-bar, looking at it either from the top or bottoni. Fig. 6 is a section taken through the handle-bar and the upper portion of the steering-post, showing the manner of securing the handle-bar to the steering-post, and also showing my preferred method of lugs and slots for preventing the rotation of the handle-bar around the upper end of the steering-post when the handle-bar is secured in an?,T of the positions desired.

A represents the steering-post or stein of the bicycle, which may be either directly or indirectly secured to the front forks, which afford the bearing for the steering-Wheel. This stein is preferably secured in a tubular bearing at the `forward end of the bicycle, as is usual.

Ii is the handle-bar, which is provided with a socket B. This socket B, it will be noticed, is so formed or constructed as to have opposite conical-shaped seats, which are counterparts one of the other.

The upper end or head of the steering-post A is formed in such a manner as to snuglT fit into the recess ot the socket B' at either side, and is preferably formed, as shown more clearly in the drawings, Figs. l and 5, namely, in the shape of a frustuin of a cone A and having a projection A2, With a screw-thread A3 projecting, which screw-thread or stud is far enough beyond the upper end of the socket Il' to engage or be engaged by a nut ai. Between the nut a and the annular shoulder o2, formed by the intersection of the projection A2 with the top of the cone A', is a conical Washer O. The shape of this washer, both in cross-section and general contour, is identical with the shape of the upper end of the steering-post,which engages the socket of the handle-bar.

Preferably I provide the nut a with an annular projection as, which engages snugly a recess or seat O'in the upper end oi the Washer C, the object of this recess and projection being to provide a ineans for sten-dying the upper end of the Washer, and hence the handle, the lower end being sustained b v means ofthe unthreaded portion of the projection A2. Extending out at either side from the upper portion of the cone A' are two studs a a4. (Shown more elearl7 in Fig. U of the drawings.) These studs engage with slots b4 h4, provided in the socket ot the handle-bar and shown incre clearly in Fig. 5 of the drawings, the object of these studs and the sockets being to prevent the rotation of the handle-bar around the upper end of the steering-post, and also prevent the inisplaceinent of the handle-bar in relation to the steering-Wheel, inasmuch as the handle-bar inust, at all times, be at right angles to the wheel. NoW,Wl1ile I have clearly shown and described my pref erred method of constructing the socket in the handle-bar in connection with the upper end of the steering-post, still I do not Wish to limit myself to this mode ofconstruction, inasmuch as, instead of using the lugs d4 at and the sockets b4 b4, the cross-section of the upper end of the handle-barinay be of some irregular shape, such as square, hexagon, or Octagon, and the socket in the handle-bar nlade to conform therewith.

It will. be noticed that in order to attain the four dirterent positions shown in Figs l, 2, 3, and of the drawings I forni the oonieal portion at the upper end of the steering-post with its axis obtuse to that of the axis of the steering-post, and by reversing,` the handle and turning the steering-post around the handle may be made to assume any of the different positions, as shown in the drawings.

1What I Claim is- In a steering' device for bicycles, the oombnation with the socket of a handle-bar having reversible bearings adapted to engage the upper end of the steering-post, of a steering- DAVID S. HITCHCOCK. Vitnesses W. E. DONNELLY, ELLA E. TILDEN.
